3.3V Common Power Supply.
2.5V Power Supply, for CPU(0:2) outputs.
2.5V Power Supply, for CPU/2 output.
2.5V Power Supply, for IOAPIC(0:2) outputs.
Common Ground pins.
A bypass capacitor (0.1µF) should be placed as close as possible to each positive power pin. If these bypass capacitors are not close to
µ
the pins their high frequency filtering characteristic will be cancelled by the lead inductances of the traces.
